Abstract

A glimpse of dark energy Cosmologists can tell from observing distant supernovae that the Universe is undergoing a phase of accelerated expansion, but the physical cause remains a mystery. The favoured explanation requires huge amounts of invisible 'dark energy', distributed across the Universe, forcing expansion via gravitational repulsion. A new survey of redshift distortions of thousands of faint galaxies provides hints as to the nature of dark-energy induced cosmic acceleration. The distortion at a redshift of z = 0.8 is consistent with the standard cosmological-constant model with low matter density and flat geometry. The current error bars are too large to distinguish among alternative origins for the accelerated expansion, but the next generation of galactic surveys, more powerful and far-reaching than the current crop, should provide much tighter constraints on the properties of dark energy.
